Recent Advances and Challenges in Ni-Base Superalloy Technologies Professor Sammy Tin Illinois Institute of Technology As one of the most important classes of high-temperature structural materials, Ni-base superalloys are critical to the continued development of high-performance turbine engines for propulsion and power generation. In order to accommodate the increases in engine operating temperatures required for improved performance and efficiency, innovative alloying concepts and processing approaches have been developed to enhance the mechanical properties of Ni-base superalloys. These technological advances can largely be attributed to the development of physics-based computational models and novel characterization tools that provide an improved fundamental understanding of the intrinsic mechanisms governing their characteristic behavior. This talk will discuss some of the advances and challenges associated with developing engineering solutions to overcome these intrinsic limitations and extend the temperature capability of polycrystalline Ni-base superalloys. Dr. Sammy Tin is a Professor of Materials Engineering in the Department of Aerospace, Materials and Mechanical Engineering at the Illinois Institute of Technology. Professor Tin’s research has focused on the composition – processing – microstructure - mechanical properties - performance relationships in polycrystalline and single crystal Ni-base superalloys. Prof. Tin is an internationally recognized expert in the field of superalloy creep, fatigue, oxidation and solidification. Professor Tin serves on the Editorial Committee for Materials Science and Engineering A and Metallurgical and Materials Transactions A. He was the recipient of the 2004 Rolls-Royce Mark Shipton Patent Award, the 2006 IOM3 Cook/Ablett Award and the 2007 ASM Marcus A Grossmann Award. He has also served as the Chair of the TMS High Temperature Alloys Committee and is currently on the Programming Committee of the 2016 International Conference on Superalloys. Prof. Tin has five patent applications and authored over 90 manuscripts in referred journals and conference proceedings.
